Windows Event Logs
These are the events that you are used to viewing in the Windows Event Viewer. While SharePoint 2010 will write to its own trace logs, it also writes events here as well. You can configure how much information SharePoint writes to the Windows Event Logs in the same way you can control how much it writes to the trace logs.
Enabling event log throttling (In Central Administration, under Monitoring >"Configure diagnostic logging"), SharePoint will only write events periodically, telling you the event is still being throttled. This keeps your Windows Event Logs from being overrun by the same message.
B: The Developer Dashboard
You aren't always handed the correlation ID all tied up with a bow. Sometimes the page will render, but there are problems with individual web parts. In those cases, you can use the Developer Dashboard toget the correlation ID and hunt down the problem. This dashboard is loaded at the bottom of your requested web page. The user browsing the page must have the AddAndCustomizePages permission (site collection admins and users in the Owner group, by default)to see the Developer Dashboard and it must be enabled in your farm.

C: ULS logs errors, but you
C: The actual details of your error will be in SharePoint's ULS log files. The key here is the correlation ID that has been listed out. You have to parse through the appropriate log file and filter down to log events that use that correlation ID. Then, within that group of items, there should be more detailed error messages about what happened.
Where to find ULS log files
They're in SharePoint's hive.Since you're using 2013, they will be in the 15 hive, which is located at:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\Logs D: The correlation ID is basically a unique error identifier (GUID) Microsoft displays on an error screen in SharePoint - and it is very useful. This error screen will also include the date/time of the error. The correlation ID is attached to every event related to the error you experienced within the SharePoint event log.
Note:
* Correlation ID
The correlation ID is a globally unique identifier GUID that is assigned to each conversation a user or process has with SharePoint.
The correlation ID is considered by many administrators to be one of the best new features in SharePoint
2010.
When an error occurs, anadministrator can use the correlation ID to track down all the events in the trace logs that pertains to the conversation where the problem occurred.
